SUPPORT.

Application filed August 22, 1927, Serial No. 214,697, in in Germany August a, 1927'.

My invention relates to a support, especially such, which has to sustain very considerable pressures and shocks and 1t consists 1n the first instance therein, that this support embodies one or several layers of thin bent wire, preferably bent or wound in form of spirals which can be made to mesh if this should be required. The wires, bent or wound in form of spirals or such like, may preferably be disposed more or less vertical- 1y to the direction of motion by loads of objects passing over them, such as railwaytrains. A plate made from the wire may be made to possess difierent degrees of strength or resisting-power in different places by changing the number of layers or by changing the size of the bends or windings, or by taking both measures together.

A further object of the invention consists in filling the gaps below rail-joints with an elastic support, preferably with an elastic support of the nature, as previously described.

A third object of the invention consists therein, that preferably in connection with a support, in accordance with the stated features, a mass will be formed consisting of asbestos-fibre, aluminium powder or such like, in combination with pitch and asphaltproducts and preferably also in combination with Epouree, which may in itself be used as a support for strong pressure and shock strains. A support of this description will show also in absence of the wire reinforcing such compressure and tensile strength and other resisting properties, that it may be deemed useful for other purposes which include a considerable strain.

A preferable combination of the mass of the support or the filling-mass consists of one part of Epoure, which is natural Trinidad asphalt freed from earthy impurities, has elasticity and a high melting point, between 150180 C. but is somewhat brittle,

two parts of Goudron, which is a distillation product obtained mainly from Trinidad asphalt and is of the nature of fatty asphalt, having a melting point between 95 and 100 C., and great toughness, two parts of coaltar pitch or brown-coal tar pitch, which are brought up to boiling point and to which one part of asbestos fibres is added. The hardness or toughness of the mass can especially be regulated by changing the quantity of the asbestos-fibre, aluminium-powder or such like to be added. The larger the quantity of asbestos-fibre or such like, which is added to the mass, the greater will be the degreeof toughness or hardness of the plate. Trinidad asphalt cannot be used alone, on account of its brittleness, but is especially adapted for the purpose when mixed with the tough Goudron. These two do not readily mix, and to make them readily mix the pitch is added to the composition.

The wire plate is preferably made to consist of spirals, which all or in part mesh. A supporting plate according to the invention may for example show throughout its full length or in certain parts of its length, several layers of spiral wire in superposition. If such reinforcements are disposed parallel to each other, the support thus formed will be specially suitable for neutralizing wavelike motions. If the support is used in conjunction with rails, the position of the direction of the spirals, being placed transversely to the direction of motion of railwaytrains or.such like, is specially suitable for the purpose of neutralizing the vibrations. T attain these objects by the mechanism illustrated in the accompanying drawings, in which: 7

Fig. 1 represents a cross-section of a plate in accordance with the invention on an en larged scale and I Fig. 2 shows the employment of plates in accordance with Fig. 1 with rail-joints, as well as a specially yielding mass immediately below the rail-joint.

Similar numerals refer to similar parts throughout the several illustrations.

In the drawing a represents spirals seen in the direction of the axis, being placed at I in three layers in superposition, partly connected with each other at II by other spirals a and at III again by spirals at IV shows a double layer of wire spirals (1 contained within a frame of wire spirals a. The wire spirals are connected with each other in a manner not shown. Z) is a mass consisting for example of Epoure, Goudron, coal-tar pitch, brown-coal tar pitch and asbestos fibre, which envelope the wire spirals inwardly and outwardly. This mass embodies especially excellent properties for taking up pressures even with varying temperature, such as will be met with for instance'in conjunction with railway construction material. In Fig. 2 0 represents the ends of rails, (Z a fish-plate, 7 an iron sleeper, common to both ends of the rails, which shows a gap between the two ends of the rails. This gap is filled with a yielding mass 9, intended to support the rails below the joint and which can be made to communicate with the ends of the elastic support, a, b. This yielding mass may also preferably consist of thin, bent wire, it necessary, in combination with a filling mass in accordance with the present invention or it may be made to consist of the filling mass only. At any rate it must consist of a yielding material of high resisting power. A support of the ends of the rails at the joint by means of a yielding mass of high resisting power, has not been known up to date. The yielding mass 9 may be preferably made use of in conjunction with a form of sleepers, as shown and elucidated in the accompanying drawing. With other forms of sleepers another method of support by the yielding mass, must naturally be introduced; I

Designs or arrangements in accordance with the present application will be capable of sustaining extraordinary strains and are especially well suited for sound damping purposes and for rendering harmless any kind of vibrations.

The thickness of the wire may be quite inconsiderable, for example 0,5 to 1 mnr, whilst the diameter of the windings or spirals may amount to 3 mm. or 4 mm.

I claim 1. A resilient bearing cushion including a layer of thin wire wound in form of helices, the planes of whose convolutions are substantially perpendicularto the pressure surface.

2. A resilient bearing cushion including a layer of thin wire, wound in form of helices, the vicinal helices chaining one another, the planes of the convolutions of the helices being substantially perpendicular to the surface of pressure.

3. A resilient bearing cushion including a plurality of layers of thin wire wound in form of helices, the planes of whose convolutions are substantially perpendicular to the surface of pressure.

4. A resilient bearing cushion including at different places a differing number of layers of thin wire wound in form of helices, the planes of whose convolutions are substantially perpendicular to the surface of pressure.

5. A resilient bearing cushion including at different places a differing number of layers of thin wire wound in form of helices running parallel to each other, with their axes substantially parallel to the pressure surface.

6. A resilient bearing cushion including at different places differing numbers of layers of thin wire wound in form of helices running parallel to each other, the vicinal helices chaining one another, and the planes of whose convolutions are approximately perpendicular to the plane of pressure.

7. A resilient bearing cushion including at different places a differing number of layers of thin wire wound in form of helices running parallel to each other and in planes substantially perpendicular to the surface to which pressure is applied, the vicinal helices chaining one another.

8. A support in accordance with claim 1, having the wire embedded in a rust prevent ing plastic medium.

9. A support in accordance with claim 1, having the layer envoloped with acoating consisting of a mixture of Epoure, and asbestos fibres.

10. A support in accordance with claim 1, having the layer enveloped with a coating consisting of a mixture of Epoure, pitch, asphalt-products and asbestos fibres.

In testimony whereof I have aifixed my signature.

RUDOLF STEIN.
